Blow Ice Signalized Warning System Design

Project description

Certain open field areas have a history of snow and sleet blowing across the road and creating slippery conditions in a relatively short section when the rest of the highway is clear and dry.  Not only does this condition violate driver’s expectations increasing risks of crashes and injuries, it also prevents MnDOT from obtaining their goal of clear roadways during the winter months.

This project will provide a design for a dynamic warning to drivers when the pavement becomes icy. Maintenance will also be informed when these conditions exist so that they may respond to the condition.

Project benefits

  • Reduce roadway departure and head-on collision types
  • Email alerts and use of camera should improve maintenance response time and efficiency
